We all know that constructors are nothing but methods in java. But, as all the methods are either static or non-static , Then, what is the type-access modifier for the constructor?

The constructors do not have a return-type.

Which of the following functions will be invoked on the function call- show(10);

Which of the following methods will be invoked when the call is-- show(10L);

class A  {
    int x=10;
    public static void show()    {
        int x=20;
        System.out.println(x);
    }
}

The Output we always get is-- 20,, But Why... What is the name of this concept??

Method-Overloading implements the principle of Compile-time Polymorphism, wheras Method Over-riding implements the concept of Runtime Polymorphism.

JVM is the compiler for Java.

What is the concept Below???

class A  {
    int x=10;
};

class B extends A  {
    int x=100;
    show()     {
        System.out.println(x);
    }
    public static void main(String... s)  {
        B b1=new B();
        b1.show();
    }
};

The program will print 100. But the concept illustrated is----
